2010

By Helmut W. Fischer, Tom Bielefeld, Former Associate, Project on Managing the Atom (MTA), September 2011–June 2014; Former Research Fellow, MTA, 2008–2011; Former Research Fellow, International Security Program/MTA, 2006–2008 and Bernd Hettwig

Helmut W. Fischer, Tom Bielefeld, and Bernd Hettwig's article "Krypton Gas Cylinders as a Source of Radiation" was published in Health Physics. Their article proposes to improve labeling and documentation standards for cargo shipments of pressurized krypton gas.

Helmut W. Fischer, Bernd Hettwig, and Tom Bielefeld presented "85Kr in Industrial Krypton Gas: Origin, Identification and Dosimetry" at the Third European IRPA Congress in June 2010. They reported on a case of transcontinental transport of krypton gas, triggering of a radiation alarm and subsequent in situ measurement by different radiometric techniques.

2008

Recent foiled and successful terrorist plots in Europe and the US (including two cases in the UK and Germany which included plans to design radiological dispersal devices in 2004 and 2005), clearly demonstrate that domestic or locally acting terrorist cells have become an important part of the terrorist threat picture. The uncovered “dirty bomb” – plots involved radioactive material of type or quantity that would not have caused much damage. Still, these observations underscore the necessity to revisit the issue of radioactive sources security in countries which may become the target of a radiological attack. This includes in particular countries in Europe, many of which in the past relied on sophisticated — but safety centred — regulations and functioning oversight institutions.

2007

By Tom Bielefeld, Former Associate, Project on Managing the Atom (MTA), September 2011–June 2014; Former Research Fellow, MTA, 2008–2011; Former Research Fellow, International Security Program/MTA, 2006–2008 and Helmut W. Fischer

MTA/ISP fellow Tom Bielefeld and his co-author Helmut Fischer focus on the problem of protecting radiological sources, preventing a “dirty bomb” attack, and putting measures in place to mitigate the effects should an attack occur.
